When going back to My Inventory from an item all of the accordion drop-downs open back up. If you want to quickly look between anything after the generic 'Items' accordion it becomes very frustrating as you have to re-collapse Items each time. I imagine this will happen with meals as well as soon as I unlock Cooking and have more than 2 Meals listed. The most frustrating part is that it appears that the accordions are re-opened after I've gone back to that page, meaning that I see what I want to open next for a split moment before I'm back looking at Items again. This is worse again on mobile as it can be difficult to hit the correct thing when trying to collapse the accordions, which opens an item, which means my progress is totally reset. This becomes agonizing when I want to look at all of my fish or super-rares, as a single mis-press means I have to start over.
Please allow previously collapsed accordions to stay collapsed in browser state in the My Inventory page when browsing back to that page, or perhaps an option to have the default be that all accordions are collapsed by default, or (also) make the accordion collapse buttons thicker, such that it is easier to press them.
